Thank you, I am so happy to have a perfectly working 2001 in such great shape, it’s a beautiful panel! I agree, a surge most likely did it in. But I’m glad I was able to give it new life again. Thank you, I’d love to get the march-time card configured. Do you know off hand what EOL resistor values I need for the zones and signals? I also have an annunciator trouble on the main control card.
